Big Bore or not - FIDDY TECH: Help, How-to, Parts & Mods

Mgleick · 08-28-2008, 01:29 PM

I just picked up a xr50 real cheap with a blown piston. My choices are to have the cylinder honed out and put a new 50cc piston in, OR I can pickup one of those trailbikes 88cc kits. I really dont want to put any more than 200 bucks into this motor. What do you guys think is my best bet?

72cc is my fav, you can get them shipped for like 120 bucks

It proble wont cost all that much more to do an 88 kit. Go for it! It gives the bike a little extra kick:YEAH

The TwoBros. 88cc kit is worth every penny IMO. The stock 50 motor has 2.6 hp. The 88 kit bumps it up to 5.7. I have the dyno graph to prove it. It comes with a cam and carb too. True bolt-on. Do it braaahh!!

If durability is the question the 88 kit will last a VeRY long time. I do not no this as a term as of 10 years of something of that manner but I have ridden the 50 Stunt/TB big bore as hard as I can for the past two years now and have had not one mechanical problem.

I hope that this can help answer your question,

Aaron
